New ultrasonic sensors for proximity detection tasks

Migatron Corp recently released two new sensor models targeted at proximity detection and displacement measurement tasks for production line applications such as high-speed counting, liquid level, and many other areas of process control. These sensors are available now from Ixthus Instrumentation Ltd.

The LCU-40APW is a self-contained sensor with an operational range from 100mm to 1m with an analogue output and pulse width output incorporated – enabling use for either fixed, factory calibrated 250mV per inch measurement (analogue) or with ToF measurement to determine distance (pulse width). The new RPS-409A-IS3 is an intrinsically safe ultrasonic position sensor for measurement ranging from 100mm to 5.5m in four range options. Its 0-10VDC output is a fixed analogue volts-per-inch value based on the unit's maximum range. This sensor is certified for usage in hazardous gas or dust environments classified as Class I, II, or III when employed with approved intrinsic safety barriers.

These sensors are characterised by fully sealed housings and encapsulated solid-state electronics utilising various materials – altogether providing extreme resilience to environments, delivering truly long-life non-contacting measurement and essentially maintenance-free operation. These sensors also provide a superior resistance to shock and vibration, infrared radiation, ambient noise, and EMI radiation.

Various models cover positional accuracies in the range of 0.5mm to 2mm with its specialist high precision RPS-412A series capable of a 5-micron accuracy and sub-micron resolution when utilised with suitable 14-bit resolution analogue-to-digital conversion electronics.

The fully sealed and highly durable LCU-40APW has a 42mm diameter PVC housing and a glass-filled epoxy resin sensing face. Powered from 11.8-30VDC with reverse polarity protection, a selection of terminal block or M8/M12 connector electrical interfacing is complemented with a choice of mating cable assemblies.

The intrinsically safe RPS-409A-IS3 sensor is housed in a 30mm, fully sealed, PVC barrel-style enclosure with a PVC sensing face. It is powered by 16-30VDC with reverse polarity protection, and its 0-10VDC calibrated analogue output is short circuit protected. The sensor provides an M12 female connector with IP67 cable assembly accessories available to order. Built-in temperature compensation provides accurate readings throughout the -40C to +60C operating temperature range.

Like most of the company's ultrasonic sensors, these new models are created to take advantage of PLC and PAC analogue input modules. The system resolution depends on the module's specification, and the zero and span values may be user-programmed.
